  In the multi-layer glass of the above document, when stained glass is fitted and fixed to all the through holes of the apertured plate, the space between the pair of glasses is partitioned in the thickness direction by the intermediate panel to form a plurality of heat insulating layers. In addition, there is an advantage that the heat insulation effect and the sound insulation effect are further improved, but the opening plate made of stainless steel is relatively heavy, and further, the weight of the stained glass is added to it, so that the overall weight increases, the carrying work load and the assembly are increased. In addition to the problem of increasing the burden of attaching work, there is also a problem that it is difficult to keep the manufacturing cost low because it is necessary to make a plurality of through holes for daylighting. In addition, when the intermediate panel is deformed due to thermal expansion, distortion due to external force, or the like, the intermediate panel may come off from the spacer side or the spacer may be damaged, and problems remain from these points.

  The present invention solves the above-described problem, and inserts a spacer so that a space is formed between a pair of opposed plate-like glasses, and the space is partitioned in the thickness direction so that a plurality of heat insulating layers are formed. Multi-layer glass with an intermediate panel placed between the glass panels enables the overall weight reduction and manufacturing cost reduction, and provides multi-layer glass that can cope with some deformation of the intermediate panel due to thermal expansion and distortion. The purpose is to do.

A multilayer polymer glass comprising the support means.

  Second, the clearance C is formed between the intermediate panel 7 and the spacer 6.

  Third, a support portion 14 having an insertion portion 14a that is open to the space S side and can insert and support the peripheral edge portion of the intermediate panel 7 is provided on the spacer 6 side to constitute a support means, and the peripheral edge of the intermediate panel 7 The support portion 14 is configured such that the clearance C is formed in the insertion portion 14a in a state where the portion is inserted.

  Fourth, the support portion 14 is formed of a U-shaped channel member fixed to the spacer 6 side, and an insertion groove serving as the insertion portion 14a is formed on the concavely recessed inner surface of the channel member 14. It is characterized by becoming.

  Fifth, a pair of channel members 14 are arranged on at least one of the upper and lower sides and the left and right sides of the square intermediate panel 7.

  Sixth, a part of the peripheral edge of the intermediate panel 7 is used as an adhesion part that adheres to the spacer 6 side, and the other part is a non-adhesion part that does not adhere to the spacer 6 side. The support means is configured by forming a clearance C in the bottom.

  Seventh, the spacer 6 interposed between the pair of glasses 4 and 5 is formed in an annular shape surrounding the space S, and the intermediate panel 7 is arranged on the inner peripheral side of the spacer 6.

  According to the present invention configured as described above, the intermediate panel is made of a resin plate that can be integrally molded and has a light-transmitting property, so that the overall weight can be reduced and the manufacturing cost can be reduced. The clearance on the peripheral edge side allows the deformation of the intermediate panel due to thermal expansion or the like, and has an effect of preventing the breakage of the spacer and the removal of the intermediate panel due to the deformation of the intermediate panel. .

  In addition, a support portion having an insertion portion that is open to the space side and can insert and support the peripheral edge portion of the intermediate panel is provided on the spacer side to constitute a support means, and the intermediate portion is inserted into the insertion portion while the peripheral edge portion is inserted. By configuring the support portion so that the clearance is formed, there is an effect that the sealing performance of each heat insulating layer partitioned by the intermediate panel can be improved and the intermediate panel can be stably supported by the support portion.

  In addition, the support portion is made of a U-shaped channel member fixed to the spacer side, and an insertion groove serving as the insertion portion is formed on the inner surface of the channel member that is recessed in a concave shape. While being able to support stably, the airtightness of each heat insulation layer improves more by a support member and an intermediate | middle panel.

  Further, a part of the peripheral edge of the intermediate panel is used as an adhesive part that is bonded to the spacer side, and the other part is used as a non-adhesive part that is not bonded to the spacer side, and a clearance is formed in at least a part of the non-adhered part side. By configuring the support means, the support means can be simplified and the cost can be further reduced.

  Since the spacer interposed between the pair of glasses is formed in an annular shape surrounding the space, and the intermediate panel is disposed on the inner peripheral side of the spacer, the space can be sealed by the spacer. In addition to the effect that it is not necessary to provide another member to improve the airtightness of the intermediate panel, there is also an effect that the intermediate panel can be supported more stably via a spacer surrounding the peripheral edge of the intermediate panel.

FIG. 1 is an overall front view of a glass window using a multilayer glass to which the present invention is applied. A glass window 1 shown in the figure mainly includes a multilayer glass 2 and a sash 3 into which the multilayer glass 2 is fitted. And.

  FIG. 2 is a cross-sectional side view of the main part showing the structure of the multilayer glass and the sash, and FIG. 3 is a perspective view of the spacer, the inner glass, and the mounting frame. The multi-layer glass 2 includes a pair of transparent (translucent) rectangular plate-like glasses 4, 5. The pair of glasses 4, 5 are arranged to face each other in a parallel state. A space 6 is formed between the glasses 4 and 5 by inserting a spacer 6 between the glass 5 and 5, and one or a plurality of (in the figure, one) intermediate panel 7 is disposed in the space S. .

  Each of the pair of glasses 4 and 5 is formed in a square shape whose vertical direction is the longitudinal direction, and one glass 4 is configured to have a larger area and thickness than the other glass 5. The thick glass 4 with a large area becomes an outer glass arranged outside the double-glazed glass 2 separating the inside and the outside of a room or the like, and the thin glass 5 with a small area becomes an inner glass arranged inside the plural glasses 2. . The outer glass 4 is fitted into and supported by the sash 3, while the inner glass 5 is supported by the sash 3 by the mounting frame 8 and supported by the outer glass 4 by the spacer 6. Incidentally, resonance is prevented by the difference in thickness of the pair of glasses 4 and 5, and the soundproofing effect is enhanced.

  First, the support structure of the outer glass 4 will be described. The sash 3 is a rectangular frame that surrounds the peripheral edge of the outer glass 4 of the multilayer glass 2, and the inner peripheral surface of the sash 3 has a peripheral edge of the outer glass 4. The recessed part 3a which can insert is formed over the whole. When inserting the peripheral edge of the outer glass 4 into the recess 3 a, the gap 9 between the recess 3 a and the outer peripheral edge of the outer glass 4 is filled with the packing 9. For this reason, the outer glass 4 is fitted into the sash 3 without a gap, and is fixed to the sash 3 integrally.

  On the other hand, the support structure of the inner glass 5 will be described. The mounting frame 8 extends in the thickness direction of the outer glass 4 and the inner glass 5 (hereinafter simply referred to as “thickness direction” or “front-rear direction”), and the peripheral portion of the inner glass 5. A cylindrical portion 8a having a front-view shape that surrounds the cylindrical portion 8a. One end portion of the cylindrical portion 8a serves as a contact end that is in contact with a surface 4a facing the inner glass 5 of the outer glass 4, From the other end portion of the shaped portion 8a, a surface on the opposite side to the facing surface 5a of the inner glass 5 facing the outer glass 4 is received so as to extend in parallel to the inner glass 5 and not further away from the outer glass 4. A receiving piece 8b to be stopped is integrally formed.

  The length of the cylindrical portion 8a in the thickness direction is set to such a length that the mounting frame 8 does not protrude or slightly protrudes from the sash 3 when the contact end is brought into contact with the outer glass 4. The outer periphery of the cylindrical portion 8 a is set to a size and shape that can be substantially fitted to the inner peripheral surface of the sash 3. On the other hand, the receiving piece 8b of the mounting frame 8 is formed in an annular shape along the peripheral edge of the inner glass 5 so as to be able to receive four sides of the inner glass 5 with the outer glass 4. Each side part of the inner glass 5 is bonded and fixed to 8b.

  After the cylindrical portion 8a of the mounting frame 8 to which the inner glass 5 is bonded and fixed as described above is inserted into the inner peripheral side of the sash 3, the outer peripheral surface of the cylindrical portion 8a is bonded to the inner peripheral surface of the sash 3. By bonding and fixing with the agent 11, the inner glass 5 is securely fixed to the sash 3 and the outer glass 4.

  The spacer 6 is formed by annularly connecting a plurality of strip-like pieces 12A and 12B (see FIG. 5) made of a rubber material, a synthetic resin, or the like that is elastically deformable in a sectional view. Specifically, two types of linear strips 12A and 12B having different lengths are prepared in pairs, and the longer pair of strips 12A and 12A and the shorter pair of strips 12B and 12B. A rectangular annular spacer is formed by connecting the four strips 12A and 12B in an annular manner so as to face each other. In addition, you may form the square annular spacer 6 by connecting the both ends of one strip | belt piece.

  Both ends of the annular spacer 6 interposed between the pair of glasses 4 and 5 are bonded and fixed to the abutting facing surfaces 4a and 5a by an adhesive, double-sided tape or the like, respectively. 6, the space S between the glasses 4 and 5 is enclosed and sealed, and the inner glass 5 is fixed to the outer glass 4.

  Further, in the state of being interposed between the glasses 4 and 5, the strips 12 </ b> A on the long side of the spacer 6 are along the left and right long sides of the inner glass 5, and the strips 12 </ b> B on the short side are the inner glass 5. When the mounting frame 8 is fixed to the sash 3 so that the inner glass 5 is brought closer to the outer glass 4 side, the inner periphery of the cylindrical portion 8a and the outer periphery of the spacer 6 By filling the gap 13 formed between them with the filler 13, the airtightness of the space S is further increased, and the heat insulation efficiency of the double glazing 2 is improved.

  The intermediate panel 7 is a rectangular plate made of a synthetic resin having high bending rigidity and transparent (having translucency) such as acrylic resin or polycarbonate, and a spacer so as to partition the space S in the thickness direction. 6, a plurality of (two in the illustrated example) heat insulating layers L are formed in the sealed space S by the intermediate panel 7. Incidentally, the intermediate panel 7 is slightly smaller in area and thinner than the inner glass 5.

Next, a support structure for the intermediate panel 7 will be described with reference to FIGS.
FIG. 4 is a sectional side view of the main part of the multilayer glass showing the support structure of the intermediate panel, and FIG. 5 is an exploded perspective view of the spacer and the support member. On the inner peripheral side of the spacer 6, a support member (support portion) 14 that is a support means for supporting the intermediate panel 7 is provided separately from the spacer 6.

  The support member 14 is fixedly attached (fixed) to each of the four surfaces on the left, right, and upper and lower sides constituting the inner peripheral surface of the spacer 6 so as to surround the peripheral edge of the intermediate panel 7. Each of the four support members 14 is a channel member having a U-shape in cross section, and each channel member 14 has an insertion groove (insertion portion) whose inner surface recessed in a concave shape due to its overall shape is open to the space S side. It is formed along the spacer 6 so as to form 14a. The insertion groove 14 a is formed in a shape and size that allow insertion of a corresponding portion of the peripheral edge of the intermediate panel 7.

  Specifically, the upper and lower portions (a pair of insertion end portions 7a and 7a) of the peripheral portion of the intermediate panel 7 are inserted into the upper and lower insertion grooves 14a, and the left and right portions (the pair of insertion end portions of the intermediate panel 7). 7a, 7a) is inserted into the left and right insertion grooves 14a, whereby the intermediate panel 7 is supported and fixed in the space S in parallel and non-contact with the respective glasses 4, 5.

  That is, by inserting and supporting a pair of insertion end portions 7a and 7a forming opposite sides of the square intermediate panel 7 in a pair of opposed insertion grooves 14a and 14a, respectively, the space in the space S of the intermediate panel 7 is obtained. Support and fix.

  In this supported and fixed state, the distance between the bottom portions of the pair of insertion grooves 14a and 14a is slightly longer than the length between the pair of insertion end portions 7a and 7a. A clearance (gap) C is formed between the bottom portion and the insertion end portion 7a when the intermediate panel 7 undergoes deformation such as expansion, contraction, expansion or contraction due to heating or cooling. In other words, the support member 14 is formed so that the clearance C is formed between the spacer 6 and the peripheral edge of the intermediate panel 7 in more detail, with the intermediate panel 7 being supported. It is configured.

  Further, in the present glass window 1, since the entire peripheral edge portion of the square intermediate panel 7 is surrounded by the four support members 14, as shown in FIG. 5, the strips 12A and 12B are formed at the stage before the spacer 6 is assembled. After fixing the support member 14 to the belt, the strips 12A and 12B are connected in an annular manner as described above so that the peripheral edge portion of the intermediate panel 7 is inserted into the four insertion grooves 14a. It becomes possible to attach and fix to the spacer 6.

  According to the glass window 1 configured as described above, the plurality of heat insulating layers L formed in the space S by the intermediate panel 7 and the four support members 14 surrounding the peripheral edge of the intermediate panel 7. Therefore, the heat insulation effect and the soundproof effect are further improved, and the crime prevention effect is also improved by the presence of the intermediate panel 7.

  It should be noted that one set of support members 14, 14 positioned on the upper and lower ends of the intermediate panel 7, one set of support members 14, 14 positioned on the left and right ends of the intermediate panel 7, and one set of support members 14. , 14 may be omitted. This simplifies the above-described assembly process and makes it possible to keep costs low. Incidentally, when the pair of support members 14 and 14 are omitted, it is preferable to omit the support members 14 and 14 on the left and right end sides of the intermediate panel 7.

  Moreover, even if the mounting frame 8 and the filler 13 are omitted from the glass window 1 having the above-described configuration, sufficient heat insulation effect, soundproofing effect, and crime prevention effect are ensured by the action of the spacer 6, the intermediate panel 7, the support member 14, and the like. Is possible.

Next, based on FIG. 6, a different part from the above-mentioned example is demonstrated about another embodiment of this invention.
6A and 6B are a side sectional view and a plan sectional view showing another embodiment of the supporting means. In the glass window 1 shown in the drawing, at least two of the four ends constituting the peripheral edge of the intermediate panel 7 are preferably not adjacent to each other (in the example shown, the lower end and the left and right ends constituting the peripheral edge). Is an adhesion location to be adhered to the inner peripheral surface of the annular spacer 6 and other portions (upper end portions constituting the peripheral edge in the illustrated example) are non-adhesion locations that are not adhered anywhere.

  For this reason, a clear lath C having substantially the same function as that described above is formed between the non-bonded portion and the inner peripheral surface of the spacer 6. That is, the support means described above is configured by bonding and fixing a part of the peripheral edge of the intermediate panel 7 to the inner peripheral surface of the spacer 6 in this way.

  According to the present glass window 1, the support member 14 is not necessary, so that it is easy to further reduce the cost.
